I've been modding the due South Seekrit Santa for eight years (which makes me the mod to have done it for the longest so far in the 17-year history of the dSSS)...and I agree with everything you've said about why not to mod exchanges anymore. It's my devotion to that particular fandom that has kept me going in that mod role, but I won't ever take on another exchange-mod role and I don't know how much longer before I start looking for a replacement mod for the dSSS.
